DUMPING Box-CAR.

SPECIFICATION forming part Ovf Letters Patent No. 734,977, dated July2S, 1903. Application filed August 15, 1902. Serial No. 119,793. (Nomodel.)

10 all whom, t may concer/t.

Be it known that I, GLENN E. SIMoNToN, a citizen of the United States,and a resident of Vanwert, in the county of Vanwert and State of Ohio,have invented a new and Improved Dumping Box-Car, of which the followingis a full, clear, and exact description. Y

My invention relates to improvements in dumping box-cars especiallyadapted for the transportation of materials in bulk, such as coal andgrain, although the car may be used for carrying coke, ore, and anyother loose dumpable material.

The primary object of the present invention is to produce a twin ordouble hopper dumping-car with means for securely closing the filling orloading openings in the roof for the purpose of excluding rain and theWeather from the grain or other bulky material loaded into the car. Theroof-doors are constructed to open freely in order to fully expose thefilling or loading openings, and they are arranged to fold snugly oversaid openings to effectually close them, special provision being made tothoroughly close the joint between the meeting edges of the doors forthe more perfect exclusionof the weather.

A further object of the invention is the provision of novel hopper-doorsespecially designed to securely close the dischargeopenings against theleakage of grain or other loose bulky material loaded into the car, saiddoors adapted when opened to assume positions which permit the granularmaterial to discharge freely and practically without obstruction fromthe doors. The inward movement of each door when closed is arrested by astop, the latter being fashioned to allow the free passage of thegranular material, so that it will not lodge against the stop.

A further object of the invention is to provide a door-actuatingmechanism for the series of hopper-doors, said actuating mechanisinserving to hold the hopper-doors se- 1 curely locked in their closedpositions and said mechanism being operable to easily open all the doorsof the group simultaneously.

A further object is to provide means for locking the roof-doors intheirclosed positions, said locking devices being held when adjusted inoperative engagement with the doors by detents or catches which areautomatically effective on the adjustment of said locking devices.

A further object of the invention is to construct the carin a manner tosecure strength and stability throughout the several parts, particularlyat the roof thereof, such roof-rafters or carlines being fashioned atpoints where they are exposed through the illing or loading openings ina manner as to prevent lodgment of the granular material.

I shall hereinafter describe the car as constructed of metallic platesandbeams or stays; but while metal of a suitable nature may beadvantageously used in the construction it is evident that wood or otherappropriate materials may be employed.

To thc accomplishment of these ends the invention consists in the novelconstruction, arrangement, and combination of parts,which will behereinafter fully described, and the actual scope of the invention willbe defined bythe claims. y

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure l is a side elevation of a dumping box-car constructed inaccordance with my invention. Fig. 2 is a vertical longitudinalsectional elevation taken centrally through the improved car. Fig. 3 isa vertical transverse section on the line 3 3 of Fig. 2. Fig. 4. isanother vertical transverse'section through the car, taken in the planeof the dotted line 4 4 of Fig. 2. Fig. 5 is another vertical trans-Verse section with the lower part of the car broken away, the plane ofthe section being indicated by the dotted line 5 5 of Fig. 2. Figs. 6and 7 are vertical sectional elevations, on an enlarged scale,illustrating two of the hopper-doors and their actuating mechanism, Fig.6 showing the doors in their closed positions, while in Fig. 7 the doorsare shown in their open positions. Fig.- 8 is a detail plan view of thehopper-door-actuating mechanism, the hopper-doors being omitted and thehangers being shown in transverse section. Fig. 9 is a .detail plan*View of a portion of the roof or deck of a car, illustrating' the meansfor locking the roof-doors in their closed positions. Fig. lO is anenlarged detail fragmentary vertical section through another embodimentof means for securing a tight joint between the hopper and its door, andFig. 11 is a vertical sectional View through a portion of the roof ordeck of a car and illustrating another embodiment of means for adjustingthe roof-doors.

The body A is carried by the longitudinal sills a, adapted to be mountedon a runninggear of any suitable character. As is usual in twin ordouble bottom dumping-cars, the body is divided, as at d in Fig. 3, suchdivision lying at the middle portion of the bottom. The bottom of thecar-body takes the shape shown more clearly by Fig. 2, by reference towhich it will be seen that the bottom consists of the outwardly anddownwardly inclined members b b' and the downwardly and inwardlyinclined members b2 b3, such inwardly-inclined members being much longerthan the outwardly-inclined members b b and the members meeting in pairsin a manner to form the twin or double hoppers. The sides and ends a2CL3, respectively,'are preferably made of metal plates joined togetherin any usual or preferred manneras, for example, by riveting theparts-and the sides of the car-body-are reinforced by the provision of aseries of vertical stays 5, the latter being riveted to the outside ofthe walls and consisting of angle-irons. As shown by Fig. 1, theangle-iron stays are united to the longitudinal sill d; but this isoptional. The roof or deck of the car-body consists of the longitudinalside plates c c', the end cross-plates c2 c3, and the middle cross-platec4. The side plates are arranged in the inclined positions shown moreclearly by Figs. 3, 4, and 5, so that they slope downwardly andoutwardly, and these side plates preferably extend throughout the lengthof the car. The side plates are provided at their outer `lower edgeswith downwardly-extending flanges 6, arranged to overlap the upper edgesof the side walls CL2, and these side walls and the side plates of thedeck or roof are united by riveting them together. The inner edges ofthe inclined side plates forming a part of the deck or roof do not meetwith one another; but they are separated and provided with upwardlyextending iianges 7. The middle cross-plate c* of the deck or roofextends -across the opening between the upwardlyflanged inner edges 7 ofthese side plates c c, and the end plates c3 are disposed to also extendacross the opening provided by the iianged edges 7, said transverseplates c2, c3, and c4 being riveted or otherwise united to the sideplates of the deck or roof. The end plates c2 c3 are also flanged andriveted to the end walls d3 of the car-body. From this description itwill be seen that the inner edges of the side plates c c and thetransverse plates d2 c3 c4 provide in the deck or roof two longitudinalfilling or loading openings B B', the same being separated by theflanged middle cross-plate c4.

rIhe'roof or deck formed by the metallic plates just described isreinforced by the employment of a series of transverse rafters orcarlines S, 9, andv 10. (See Figs. 2, 3, 4, 5, and 11.) Each rafter orcarline is made in a single piece of channeled metal, preferably frompressed steel, and said rafter or carline has inclined members joined bya central crest member. The rafters (indicated at 8 and 9) extend acrossthe loading-openings B B', and these rafters are pointed, as at S inFigs. 8, 4f, and 11, said pointed parts of the rafters minimizing thelodgment of material when it is being loaded into the car through one ofthe filling-openings. The other rafter (indicated at 10) lies beneaththe middle transverse plate c4 of the deck or roof, and it is providedwith a long horizontal portion 10. (Shown by Fig. 5.) The rafters aresecurely riveted to the side members c c of the deck, and at their endportions they are united to the vertical stays 5 on the side walls, suchunion between the stays and the rafters being preferably eifected by theemployment of rivets, which pass through the upper ends of the stays,the side walls of the car-body, and the' end portions of the rafters. Itwill be seen that the side walls and the deck or roof are stayed andreinforced by a metallic skeleton framework consisting of the series ofvertical stays and the series of rafters, thus materially increasing thestrength and stability of the car-body.

The filling or loading openings B B' are adapted to be tightly closed bythe employment of doors in order to protect the material loaded in thecar from the action of the weather. I have preferably arranged thesedoors in pairs, (indicated at C C' and D D.) The doors C C/ are adaptedto close the opening B, while the other pair of doors serve to close theother illingopening B'. These doors are preferably arranged to swinginwardly toward each other, although, if desired, the doors may bemounted on the roofplates c c to slide thereon, asin Fig. 11. Theswinging doors are connected to the roofplates c c by hinges, which areof the class known as link-hinges, in order that the doors may swingoutwardly from the iiangcd edges 7 of the deck-plates in a manner tofully expose or open the loading-openings B B. The detailed constructionof these hinges is shown more clearly by Fig. 1, from which it will beseen that each hinge consists of a member 1l, adapted to be fastened tothe deckplate, another member 12, fastened to one of the doors, and alink 13, which is pivoted to the members 11 12. A series of thesehinges, preferably two in number, is employed to connect each door tothe deck-plate, and the hinges thus provide two points on which the doorcan swing or turn on horizontal axes. Each door is provided with adownwardly-extending iange 14: at its outer edge, said flange varrangedto overlap the upwardly-extending 'flange 7 of the deck-plate. The doorC or D of each pair is provided at its inner free edge ICO with thedownwardly-extending lip or flange 15, while the companion door C or Dof the pair is provided at its inner edge with an upwardly-extending lip16 and with a supplemental or auxiliary lip 17, said lips 16 and 17being disposed in parallel relation, so as to form a channel or troughadapted to receive the downwardly-extending lip 15 of the firstmentioneddoor. This construction requires that the door C or D shall first beclosed over the filling-opening in a position to present an open channelor gutter to the flange 15 of the other door C' or D'. The door which isprovided with the single lip or flange 15 is equipped with a shield 1S,the latter being united in any suitable way to the outside of the door Cor D and arranged to extend beyond the flange 15, said shield adapted toextend over the joint between the flanged edges of the doors whenclosed, thereby eifectually excluding rain or snow at the channel orgutter on the door C or D. From this description it will be seen thatthe doors are hinged to the deck or roof in a manner to closely t aroundthe flanges 7, and the meeting edges of the doors are securely closed bythe flange 15 entering the channel or gutter between the flanges 16 17and by the shields extending over the joints.

I have also provided a novel locking contrivance for holding the pairsof doors in their closed positions, one of these locking contrivancesbeing located at the ends of the pairs of doors, as shown by Fig. 1. Thecontrivance which I prefer to employ consists of the rock-shaft 20,arranged transversely across the deck or roof at the middle portionthereof, said rock-shaft being journaled in bearings or straps 19, whichare attached to the end plates c2 or c3 or to the middle cross-plate c4.(See Figs. 1, 2, and 9.) The rock-shaft is provided at pointsintermediate of its length with the lips or studs 21, arranged tooverlap projections on the end portions of the doors, and one of theselips may be provided with an aperture adapted to receive a seal 22, thewire of which seal may pass through a projection on one of the doors, asindicated substantially by Fig. 9. The rock-shaft 2O is also provided atone end portion with a crank-arm 23, which is arranged to turndownwardly between a pair of plates or standards 2l 25, the latter beingsecured firmly to one of the deck-plates, as c. These standards arespaced far enough apart to receive a crank-arm of the rock-shaft, and onone of the standards is mounted an automatic latch 26. I prefer to pivotthe latch to the standard 25 and to arrange the short arm of said latchin the path of the crank-arm on the rock-shaft, whereby the latch isadapted to be turned on its pivot when the rock-shaft is turned intolocking engagement with the doors, said latch being adapted toautomatically engage with the crank-arm and to return to its raisedposition byA gravity, the outer longer end of said latch bearing againstthe deck-plate in order to hold the latch normally in its operativeposition.

It will be seen that the rock-shafts may be easily manipulated towithdraw the lips or studs 21 from engagement with the doors, it beingnecessary to first release the latches from the crank-arms 23, wherebythe doors may be released ain/d thrown to their open positions in orderto expose the loading-openings; but when it is desired to close theopenings, the doors should be folded inwardly and the rock-shaft shouldbe turned in a direction which will bring its lips or studs 21 intoengagement with the doors and its crank-arm into engagement with thelatch 26.

The deck of the car is provided with running-boards, as indicated at 2728. As shown by Figs. 1, 2, 3 and -l of the drawings, these'running-boards may be fastened to the doors which close thefilling-openings, so that the running-boards may be adjusted out ofposition when the doors are open; but I do not desire to limit myself tothe employment of the running-boards on the doors, because I am awarethat the running-boards may be secured to the inclined side members ccof the deck or roof, as shown by Fig. t.

The members b b of the bottom are provided with the discharging-openingsE E', each member b b being provided with an outwardly-extending flange29, which surrounds the discharging-opening. The members b o' are alsoprovided with the stop strips or blocks 30, the same being secured tothe hopper-bottom within the discharging-opening. Each stop strip orblock is made from a single piece of an gle-iron and secured within thehopper-bottom, so as to present a sloping face to the material, while anabrupt shoulder or ledge is formed in the path of the hopperdoors F F'.It will be understood that the hopperbottom is provided with four discharge-openings, two of which are in the members l) Z1 on one side of thedivision d', while the other discharge-openings are in the members l) bon the opposite side of the division a. The hopper-doors F F areconnected in pairs with an actuating mechanism, to be presentlydescribed, and the hopper-doors are hinged individually to the members bb', such hinges being indicated at 31 and located at the upper edges ofthe doors. The hinges may be of any substantial construction approved bythose skilled in the art, and they serve to fasten the hopper-doorsdirectly to the members Z) b of the hopper-bottom. These members arealso provided with reinforcement-plates 32, which are preferably ofangleiron and riveted to the members along the upper flanged edge 29thereof and adjacent to the points where the hinges 3l are fastened,said stays serving to reinforce that part of the hopper-bottom to whichthe doors are hung, because the hinges 31 are fastened to the stays aswell as to the hopper-bottom.

Each door F F" is provided with a marginal IOO iiange 33, and the upperedge of the door is reinforced by a stay 34, similar to the stay 32 onthe hopper-bottom, thus making provision for the substantial attachmentof one leaf of the hinge 31 to the hopper-door. The hopperdoors F F arearrangedl to close inwardly within the iiange 29 of thedischarge-opening, and the joint between the lower edge of the flangeddoor and the iianged discharge-opening is adapted to be securely closedby yieldable members, which may be provided either on the free edge ofthe door or on the lower iianged edge of the discharge-opening. In Figs.6 and 7 of the drawings the yieldable members are represented in theform of metallic plates 35, which are bent or doubled, so as to overlapthe inner face of the door and provide an edge for the passage of rivetsby which the bent plate may be securely attached to the door. Theangular free portion of the plate forming the yieldable member is andthe yieldable member 35.

disposed in opposing relation to the flange 33 of the door, and it liesat an incline or angle thereto, whereby the yieldable member is adaptedto frictionally engage with the fia-nge 29 of the discharge-opening. Ifdesired, this yieldable member may be extended or carried around threeof the side edges of the door; but in Figs. 2, 6, and 7 I have shown theyieldable memberV at the free edge only of the swinging hopper-door.

In Fig. l0 of the drawings I have illustrated another embodiment ofmeans by which the tight joint between the door and the hopperbottom maybe secured. In this iigure of the drawings the section 36 of thehopper-bottom is provided with an offset keeper-flange 37, which isapplied to the outer or under face of said plate 36, while the yieldablemember 35 is bent so as to lie within the space formed between thekeeper-flange and the hoppersection 36, said yieldable member having anedge portion 35b extended over the upper inner face of thehopper-section 36, whereby the keeper-flange and the yieldable membermay be riveted by a single row of rivets to the hopper-section 36. Thedoor F2 is bent at its lower edge to form the iiange 38, whichis-reinforced by a stay-plate 39, and against the under face of the doorF2 is applieda shieldplate'40, the lower edge of which is extended orprolonged beyond the ianged edge 38 of said door. A'stop-strip 4l isitted over the vstayplate 39, and this stop-strip, the stay- Ireceivethe doubled edge of the yieldable member 35 between the stop-strip 4land the stay-plate, while the flange 38 and the ottstanding portion ofthe stay-plate are adapted to enter into the space between the keeper 37This makes the yieldable member engage frictionally with the stay-plate,while the door-flange 38 engages in a similar way with the keeper 37,and the edge of the shield-plate extends beyond the overlappingfrictional joint between the hopper-bottom and the door, whereby theescape of material is effectually prevented through the door-opening ofthe hopper-bottom.

It will be seen that the j onts between the hopper-openings and thedoors are eiectually closed bythe provision of yieldable members, and inorder to prevent leakage of material between the upper hinged edge ofthe hopperdoors I prefer to extend the sections b b of the hopper-bottomacross the joint at the upper edge of the door-opening, such extensionsbeing indicated at b5 in Figs. 6 and 7.

42 indicates the hangers, which are firmly secured to the inclinedsections b b of the hopper-bottom, said hangers being located onopposite sides of the division a in the car-bottom. Each hanger isconstructed of channeled metal in the form of a stirrup or yoke, asshown more clearly by Figs. 6 and 7, and said hanger being iianged atits ends for secure attachment to the hopper-bottom. The hanger isprovided with a vertical slot 43, through which passes a shiftable boltor spindle 44, the latter carrying an idle chain-wheel or grooved pulley45. This pulley or chainwheel is loosely mounted on the bolt or spindle,and it is arranged to travel with said spindle freely through the s lot43 in a vertical direction when the door-actuating mechanism isoperated.

The bolt or spindle 44 serves to pivot-ally connect the inner ends oftwo pairs of links, (indicated at 46 46 and 47 475k) One pair of links,46 46, is pivotally attached, as at 46, to angle-plates 48, firmlysecured to the under face of one of the doors F, while the otherpair oflinks, 47 47 are similarly pivoted at 47 b to other angle-plates 49,secured firmly to the other door F. (See Figs. 6, 7, and 8.) r The linksforming each pair are disposed in converging relation, as shown byFig.8, in order to bring the inner ends of the two pairs of links intooverlapping order and compactly dispose them with relation to the bolt44 and the chain-wheel 45, whereby the inner ends of the two pairs oflinks may be united pivotally by a swinging bolt or spindle. I prefer tomake each link 46 46 47 47 in sections and to thread the inner ends ofthe linksections in a manner to receive a couplingsleeve 50, the latterbeing interiorly tapped with right and left hand threads adapted toengage with similar threads on said link-sections and to be rotatedthereon in one direction or the other for the purpose of lengthening orshortening the link, whereby the series of four links may be extended orcontracted to secure nicety in the adjustment of the door-actuatingmechanism, so as to firmly close the two doors of the pair.

5l designates a bolt-lifting chain which is connected by a loop orclevis 52 to the spindle IIO or bolt 44, said chain passing upwardlyfrom the bolt and over a guide wheel or roller 53, mounted in the-upperpart of the hanger 42, after which the lifting-chain 5l is extended toawinding-shaft 54, said end of the chain 5l being coiled in onedirection around said shaft and attached thereto in any suitable way.Another chain, 55, is employed to lower the spindle or bolt 44, saidchain being coiled on the shaft 54in an opposite direction to the chain5l. The lowering-chain 55 is carried in a downward direction from theshaft 54, and it passes beneath a guide roller or sheave 5G, the latterbeing mounted in the hanger near its lower end. This chain 55 is carriedacross and in engagement with the shiftable chain wheel or pulley 45 onthe arbor or bolt 44, and the free end of said lowering-chain is madefast to the hanger by means of a bolt 57, the latter being secured inthe lower part of the hanger and on the opposite side from the lowerguide wheel or sheave 56.

The winding-shaft 54 extends through the two hangers 42 and through theinclined middle portion of the hopper-bottom, and this shaft 54hasattached to it the winding-chains 5l and 55, which are associated withthe two pairs of hopper-doors, whereby one shaft 54 is adapted tooperate the actuating mechanisms for the series of four hopper-doors.Any suitable means may be adopted for locking the winding-shaft 54against accidental rotation, and in Fig. l of the drawings I have shownthis shaft as provided at one end with a ratchet 5S, with which isadapted to engage a pawl 59, that is held in its operative position by adetent GO. It will be understood, however, that any suitable form oflocking device may be provided for the winding-shaft.

In Figs. 2 and 6 of the drawings the hopper-doors are shown in theirclosed positions, and the spindle or bolt 44, together with theshiftable sheave or chain-wheel 45, lies at the lower part of the slot43 in the hanger. To open the hopper-doors, the operator turns thewinding-shaft 54 by a wrench or other suitable implement, and therebywinds the chain 5l on the shaft and at the same time unwinds the otherchain 55 from the shaft. This operation of winding the chain 5l liftsthe bolt 44 and the chain-wheel 45, and the upward movement of said boltdraws the pairs yof links inwardly and upwardly to the positions shownby Fig. 7, whereby the doors F F' are swung to their open positions, thechain 55 taking the position shown by Fig. 7. The material can now bedischarged freely through the openings E E in the hopper-bottom, butbefore the car is again loaded it is necessary to close the doors. Thiscan be easily accomplished by turning the shaft 54 in a reversedirection, so as to uncoil the chain 51 and to coil the chain 55 on theshaft. This chain 55 pulls downwardly on the shiftable bolt 44, be causeone end of the chain is fastened at 57 lower guide-sheave 56. The pullof the chain 55 is exerted on the shiftable pulley or chainL wheel 45 soas to force the bolt 44 downwardly, and the bolt thus acts to press thelinks in opposite directions, and thereby close the doors F F' withinthe flanged discharge-open# ingsE E', the joints between thedoor-openings and the doors being securely closed by the yieldablemembers and by the extended 'lower edges of the sections Z) b of thehopperbottom.

I do not wish to limit myself to this form of device for operating thehopper-doors, as, if desired, any other suitable device may be employedfor the purpose.

Having thus described my invention, I claim as new and desire to securebyLetters Patentl.
